The invention discloses a portable online detection device for particulate matters in an environment, which comprises a portable detection box, a detection mechanism arranged in the detection box anda sampling pipe connected with the detection mechanism, and the detection mechanism comprises an upper air channel assembly communicated with the sampling pipe and a lower air channel assembly communicated with the upper air channel assembly; an air filtering belt is arranged at the opening part of the lower air channel assembly, a movable air channel assembly is arranged at the upper part of theair filtering belt, the movable air channel assembly moves upwards to make room for the upper part of the lower air channel assembly, so that the air filtering belt enters; a detection unit emitter and a detection unit receiver are respectively fixed in the upper air channel assembly and the lower air channel assembly; according to the online detection device, the detection mechanism is fixed through the portable detection box, and the online detection device is convenient to carry and wide in application range; the movable air channel assembly moves up and down according to the lever principle, the structure is simple, the detection modules arranged in the upper air channel and the lower air channel are fixed, the overall failure rate of equipment is reduced, and the detection accuracy isimproved.
Description
technical field [0001] The invention belongs to the field of detection devices, and more specifically relates to a portable on-line particle detection device in an environment. Background technique [0002] In recent years, with the continuous advancement of urbanization and industrialization, atmospheric particulate matter has become the primary pollutant affecting the ambient air quality of my country's cities, especially in spring dust weather, autumn straw burning period and winter heating period. Particulate matter mainly refers to respirable particulate matter (PM10, that is, particulate matter with an aerodynamic equivalent diameter of 10 μm or less) and fine particulate matter (PM2.5, or particulate matter with an aerodynamic equivalent diameter of ≤ 2.5 μm), which can be divided into primary particulate matter and secondary particulate matter. [0003] In the prior art, the detection principle of the particle detection equipment in the air is mainly to pass the air ...
